' ZloaZZ culzom itmay-concern} .Be it known .that .1, Lane FLARSEN, a citi- -'Zen of the Dominion of-fianada and a resident ofiOcean Falls, Province 0f .British Columbia, Dominion of Canada, have inventedga new and usefullmprovement in 'Gradling .Booms for Cordwood, of which the following is tit specification. I

V The obj ect of my invention is. to provide me ans for; conveying wood or wooden .llilo c-ks or similarsubstances on a water way, which isadaptedto be loaded and unloaded inn nunimum amount of tnne.

. Much di flicul ty ha s been encountered .i

transporting loose floatable. objects such cor. "wood because .a great quantity has to conveyed. at onetime to make it profitable and also the samemust betransported with the minimum: amountof handling. Scows and the like .necessitate unloading by hand which renders them impractical for thisuse and floats, as now. constructed, are not adaptable because the blocks are relatively small and are forced away from the retaining logs and are'lost in transit.

My boom is made in the form of a-cradle comprising a plural sided frame made of logs connected together at their adjacent ends, a net secured at all sides except one to adjacent members of said frame, means for releasably fastening the remaining side of the net to the other frame member, dogs adapted to be secured to one frame side, and provided with eyes, eyes provided on one frame member, a cable inserted thru the said eyes of said frame-member and said net side for lacing these parts together, whereby said net when fastened all the way around to the frame members constitutes a cradle for holding articles mentioned and the releasable side of said net may be unfastened to discharge these articles.

These and other objects I have attained in the device shown in the accompanying drawings, in which:

Fig. 1 is a plan view of my cradling boom and shows how thefour sided frame is made up and braced;

Fig. 2 is a section taken on the line 22 of Fig. 1 and shows how one frame member can be made releasable so as to allow the float to be swung out and allow the contents of the cradle to be floated out;

Fig. 3 is a diagrammatic representation of my cradling boom filled to capacity, with cordwood or wooden blocks; and

over the top of the load to hold the same Fig. 4 .is .adijagrammatic representation liowthe boom can .befswiing open .to allow theblocksto be removed. i 3 The boomismade up ofa four-sidedfloatand d which are held' together-in the water by. chains 6, f, g and-.7. This frame sup- .ofa portion of my cradling boom and shows ing frame whichisof;sufficient.buoyancy.to .floatthe meshedwiresianda relatively large. load. The frame ismade .o'f'slogsa, Z), 0

ports a wire mesh of cable twhich is spaced so .asto meet the conditions of nsage'of-the boom. This. meshiisconnected to the boom fonflthree .sides, the other-.side, gl.being releas- ..ably-.secure'd to thelogdnby' means of;t he

cable j. The cable j is lfastenedat one end fastened to one edge of the i wire mesh. The. cable. 9 is also: run thru. a .serlesof-ey'es m whichare attached to the shortisectio ns to the lower end 'o'fthe log a as iat '70 and of cable niandattache'd tothe' f The I sections of cable a can eitherbe wrapped.

around the log permanently or else fastened to the log (1 by means of dogs'o. The cable j is alternately placed thru an eye Z, thence thru an adjacent eye m and thus thru another eye on and so on until the boom log 03 is laced to the mesh wire its entire length. The other end of the cable isremovably securedto the boom log a as at p and the releasable boom' chain' g is also releasably 7 In rough water a wire mesh can be placed I from being washed ofi' by the waves, or any variation such as throwing ropes over the top of the float can be used to combat the weather conditions. When the float has reached its. destination these supporting ropes or mesh can be removed from the top of the load'and the cable 3' can be untied and the boom chain 79 can be. released- The cable can be removed from the eyes and allow the boom (Z to be floatedout as shown in Fig. fl. This allows the edge 9 of thewire mesh to drbp below the surface of the water,

elongate 'floats connected together at' their because of the release of its float and thus allows the contents to be floated off rapidly.

Tow logs r are fastened to the member I) by chains 8 to provide a means for towing a the boom. Bracing cables 25 can be placed across the corners of the boom to prevent buckling.

I claim:

1. A boom of the character described, comprising a plural sided frame made of adjacent ends,'a net secured at all sides except one to ad acent members of said frame,

'means for releasably fastening the remaining side of the net to the other frame member, whereby said net when fastened all the way around to the frame members constitutes a cradle for holding art cles mentioned and the releasable side of said net may be unfastened to discharge these articles.

2. A boom of the character described, comprising a plural sided frame made of elongate floats connected together at their comprising a plural sided frame made of elongate floats connectedtogether at theirv adjacent ends, eyes'provided on one frame member, a net fastened at; all sides except one to adjacent members of said frame, and

provided with eyes along its remaining side, a cable inserted thru the said eyes of said frame-memberand said net side for lacing these parts together, whereby said net when fastened all the Way around to the frame members constitutes a cradle for holding articles mentioned and the releasable side of said net may be unfastened to discharge these articles. a

4:.1A boom of thecharacter described,

comprising a plural sided frame madeof logs connected together at their adjacent 7 ends, dogs adapted to be secured to one frame side and provided with eyes,-a net fastened at all sides except one to "adj acent members of said frame, and provided with eyes along its remaining side, a cable inserted thru the said eyes of said frame-member and said. net side for lacing these parts together, whereby said net when fastened all the way around to the frame members constitutesa cradle for holding'articles mentioned and the releasable side of said net may be unfastenedto discharge these articles.
